Abstract

A sensor card for determining analytes in liquid and gas samples with films connected to one another in sheetlike fashion, namely a sensor film facing the sample with openings and a covering film remote from the sample with openings for electrical tapping, at least one sensor being provided and arranged between the sensor film and the covering film. There is provided between the sensor film and the covering film at least one intermediate film, in which cutouts are provided, the sensor being arranged in one of the cutouts. The sensor card provides a homogeneous thickness, which brings about a reliable sealing of the flow channels for the liquid sample if the sensor card is connected to a plate that partially forms the flow channels within the analysis system. Furthermore, the invention relates to a method for producing such a sensor card.
